Each still needs its own identity and assay. Quote them as a custom BOM (F07).

A single blend weight does not identify the amount of each active. Caffeine as a named second active: see FAQ.

Eleuthero and Siberian ginseng are the same commercial root when the species is Eleutherococcus senticosus. Panax ginseng (Asian / Korean / red ginseng) and American ginseng (P. quinquefolius) are different species with ginsenoside markers.

When both roots share one capsule, specify each species and assay (F05). A ginseng-led brief belongs on the ginseng supplement manufacturer page.

Keep E. senticosus / eleuthero on the specification. Whether Siberian ginseng may appear on the destination label is a naming field.

A usable PO names species, root, markers + method, milligram basis, and the label name. How standardized botanical POs are written: standard extracts.

Eleutheroside B is syringin. Eleutheroside E is the paired lignan marker. Public herbal monographs commonly discuss B and E together as the quality pair for E. senticosus root. About 0.8% to 2.0% B+E is a frequent commercial window on extracts. Two factories can print the same percentage and still have made different extracts until method and milligram basis match. References.

Some destination files name isofraxidin or flavonoids when the customer specification includes them. Soft extract or paste is quoted for bulk or liquid paths.

Root powder vs standardized extract: which should a brand choose?

When a brand usually stays with root powder (F02) — the panel will print root milligrams only; the capsule or stick already holds a gram-scale fill; finished-unit B+E assay is not in the budget yet.

When a brand usually chooses B+E extract (F01) — Supplement Facts will print a marker %; the hard capsule must stay small; two extract COAs need a comparable HPLC pair.

Where the 0.8 percent number comes from

USP-NF Eleuthero and Ph. Eur. Eleutherococcus root texts commonly specify a minimum sum of eleutherosides B and E on dried root — often discussed as 0.08%. The EMA HMPC assessment of Eleutherococcus senticosus radix cites that Ph. Eur. root floor. The WHO monograph Radix Eleutherococci treats B and E as characteristic markers. Those documents describe herbal-substance / herbal-medicine quality for dried root.

A commercial extract COA at ~0.8% B+E is a purchase specification on concentrated dry extract — about ten times the dried-root floor because the material is no longer whole root. A Chinese Pharmacopoeia syringin (B-only) line maps to a B+E pair only when the PO names both markers. EMA traditional-use wording is a herbal-medicine file; U.S. supplement panels follow structure/function rules.

Finalize before sampling: species = E. senticosus · root · powder vs ratio vs B+E extract · B+E % + HPLC (or the named alternate) · mg basis · eleuthero vs Siberian ginseng on the label · incoming vs finished assay · origin statement yes/no.

Many RFQs request “0.8% standardized” without defining eleutherosides B+E or total saponins.

Why the assays diverge

• Eleutherosides B and E are lignan / phenylpropanoid glycoside markers, typically quantified by HPLC against named reference standards.
• Total saponins quantify triterpenoid saponins and related glycosides by another method.
• Panax ginsenosides are saponins. Eleuthero’s default export marker pair is eleutherosides B and E.
• Two COAs can both print 0.8% and still fail qualification when one method is total saponins and the other is B+E HPLC.

• We also see COAs that report only syringin (eleutheroside B) when the PO asked for combined B+E.

Lock three fields before anyone quotes: the analyte (B+E pair, or the saponin method), the named method, and whether the number applies to the incoming extract or the finished unit.

Representative RFQ wording.

Trade-off: Raising B+E at a fixed 300 mg extract increases calculated marker milligrams and can shrink capsule size. Rank quotations on marker, method, milligram basis, and finished assay.

What we see on briefs: U.S. private-label projects often start at 0.8% B+E in a hard capsule. EU-bound files often spend more time on whether Siberian ginseng may be printed. China-origin COAs sometimes list total saponins — map the method before treating the lot as equivalent (Purchasing Mistake).

Custom B+E targets are quoted when the customer specification names them.

Commercial E. senticosus root is discussed from Northeast China, the Russian Far East, and sometimes Korea. “Siberian” in the alias refers to the species’ historic range. Origin on the lot is confirmed when the label will state it.

Name origin on the PO when the label will state it. Lot-to-lot identity and the pesticide / metals panel matter more than a country name on the spec sheet. Wild vs cultivated is a sourcing note when origin is labeled.

High-level path for a dry extract used in capsules or tablets. Solvent, concentration, and the release assay follow the extract file.

Harvested root → clean → dry → mill → extract (water or hydroethanolic, as specified) → concentrate → dry → standardize to the named assay (B+E HPLC, or another method if that is the real file) → incoming QC → release to production.

Ratio (5:1, 10:1) describes a concentration story when a real DER is on the file. Residual solvents belong on the panel when an organic solvent is used. Hydroethanolic extraction is frequently used for dry extracts destined for capsules.

Need botanical identity or the lowest ingredient cost? → Root powder (F02).
Need a standardized number on the label? → B+E extract, most often ~0.8% (F01).
Need a smaller capsule? → Higher-assay B+E when the customer specification names it.
Need extract without a B+E percentage? → Named ratio (F02).
Need vegan? → HPMC hard capsule.
Need a finished-unit guarantee? → Incoming and finished assay, regardless of grade.

Freeze labeled milligrams and the basis (extract vs root) before comparing quotes.

Frequently requested labels for B+E-specified root extracts use 200, 300, or 400 mg extract per serving. Public research on named preparations is development context for those products; it does not transfer to a root-powder stick.

How much eleutherosides are in a 300 mg extract?

Calculated marker milligrams apply when the B+E percentage is on the extract as filled and the HPLC method matches the COA. A finished-capsule guarantee requires a finished assay.

Label extract mg × (B+E %) equals marker mg when basis and method match. Combination formulas name every active in milligrams. Overage follows stability data.

Send Your Brief

Align these fields on one sheet before you rank price. Send two supplier COAs with the RFQ — we map marker, method, and milligram basis against the intended label claim before quoting. For how to read a COA in general, see How to Read a COA.

Two COAs that both print “0.8%” become comparable when marker and method match.

Why two eleuthero quotes can differ by ~40%

A cheaper quote that used root powder against a 0.8% extract RFQ is a different specification and a different price. Freight is quoted separately from the unit cost.

Send two supplier COAs

Example. The RFQ asked for 300 mg, 0.8%, hard capsule. The attached supplier sheet was 300 mg eleuthero root powder with no B+E method. That is root powder priced as a standardized extract. The quotation waited until the milligram basis and marker were rewritten.

Supplier switch mid-project: Changing the extract supplier requires a new qualification because solvent profile, density, particle size and finished potency may change.

Request a Sample / COA

A finished eleuthero SKU is usually sold as a botanical in an energy or stamina assortment, as a supporting ingredient on an F03 / F04 adaptogen BOM, or next to Panax as a second species (F05). Structure/function wording must follow destination-market regulations.

United States: dietary-supplement structure/function rules. European Union: authorized health-claim lists. EMA traditional-use wording on Eleutherococcus radix is a herbal-medicine file.

Market-dependent items

Can you use the same artwork worldwide? Usually no. Destination files differ on:

Product name (eleuthero vs Siberian ginseng) · Claims · Warning statements · Supplement Facts format · Language

Possible complaints include gastrointestinal discomfort. Occasional stimulation or blood-pressure sensitivity belongs on the warning set when the destination market requires it. Incidence varies by formulation and published evidence, so warning language is developed according to destination-market requirements.

Pregnancy or lactation is not a default SKU. Infant products are not manufactured here. F03–F05 each add a second botanical interaction review. Caffeine as a named second active is a different specification from F06.

Qualification path: Supplier qualification → raw-material COA review → identity confirmation → incoming QC → production release → finished-product testing → QA approval and batch COA.

Customer-supplied raw material follows the same path. Changing the extract supplier requires a new qualification because solvent profile, density, particle size and finished potency may change.

Results outside the agreed specification go on hold for investigation. The batch is released only after the deviation is closed under a documented QA procedure.

Processing losses, blend variability, and finished-product testing mean incoming vs finished potency should be named on the PO.

Example incoming QC panel

Project requirements determine the testing panel. Methods are agreed on the specification.

Analytical methods on the finished file

Identity · HPTLC · HPLC (B+E or the named alternate) · loss on drying · bulk density · heavy metals · micro · residual solvents as agreed. In-house lab plus SGS/Eurofins when the RFQ requires a third-party report. Quality control.

Typical manufacturing problems on the line:

Send two supplier COAs

Eleutheroside content can move with moisture, heat, light, oxygen, and pack. Hygroscopic B+E powders usually need an induction seal and desiccant in the pack file — see moisture control.

Dating comes from formulation, pack, storage, and a stability study for that SKU. Sample lead time (7–15 days after spec lock) is a sample clock.

Softgels, when an oil companion is on the BOM, need a dry pack after encapsulation.

Supplement Facts must match E. senticosus, root, and milligram basis on the COA. If the panel prints B+E, the method has to point back to the specification. Whether Siberian ginseng may appear is a destination-market file (see Market-dependent items). Bottle counts are often 30, 60, 90, or 120.

Planning quantities. Final MOQ depends on formula, packaging, and production setup.

Dual-assay combos and a tight B+E finished assay add time before the sample clock. Bulk kg MOQ and finished-unit MOQ are separate.
